不同植物驯化的土壤微生物对小麦生长的影响
Effects of soil microorganisms domesticated by different plants on wheat growth
摘要
Abstract
In order to explore the effects of soil microorganisms domesticated by different plants on wheat(Triticum aestivum L.)growth,a controlled experiment was conducted using the cultivar Jimai 22 as the target crop.Seven treatments were established,in-cluding non-inoculated microorganisms control(CK1),inoculation with wheat-domesticated soil microorganisms(CK2),inoculation with Chinese cabbage(Brassica rapa)-domesticated soil microorganisms,inoculation with green foxtail(Setaria viridis)-domesticat-ed soil microorganisms(T2),inoculation with alfalfa(Medicago sativa)-domesticated soil microorganisms(T3),inoculation with abandoned farmland soil microorganisms(T4)and inoculation with woodland soil microorganisms(T5).The results showed that all treatments significantly affected wheat aboveground and belowground biomass,with T1 showing the highest biomass accumulation.Sig-nificant differences were observed in plant height,leaf area,specific leaf area(SLA),and root-to-shoot ratio among treatments.Tran-spiration and photosynthetic rates varied significantly across treatments.Photosynthetic rate showed a significantly positive correlation with plant height(r=0.74,P<0.001)and a significantly negative correlation with SLA(r=-0.49,P=0.030).In summary,soil microor-ganisms domesticated by different plants affected wheat growth significantly,and this might be mediated by changes in wheat energy allocation strategy and physiological status.The research indicated this method was feasible and had certain potential in regulating wheat growth.关键词
